Finding and replacing text in your family file is irregularly needed, but can save you time when you can use it. Turning over this tedious task to Reunion makes more family history research time available to you. That is, provided you carefully define your search criteria and backup your Reunion family file first!
Reunion has search and replace well covered everywhere except source citation details. The fields within the source record are all available to the Find -> Replace feature on the menu-bar–no problem there.
The trouble is that source detail isn’t a field in the source record and it isn’t a field in the event or fact. It’s a link between a source record and an event or fact. This is as it should be; it allows you to cite a single source for multiple events and facts and on different person records.
